Synergy in Action

Orphan Diseases Working Group Activity / Deliverables

Chairs: Joan Busner, PhD; Gahan Pandina, PhD

Upcoming Activity: Working Group Session, 2022 Autumn Conference, 8-9 September 2022, Boston MA: The working group will have a discussion to brainstorm on a stakeholder consensus process to drive development of better methods and endpoints in Orphan Disease. Other potential areas of focus for the coming year for the group will be discussed, including potential topics and speakers for a future full or half day ISCTM session.

  • Group to design a half-day session on patient centricity for a future ISCTM conference
  • Consideration of a white paper on best practices in needs of orphan drug studies, such as inclusion of caregivers in study design and implementation, need for streamlined approach to novel endpoint development, etc.
  • Identification of challenges in orphan drug developing, including real-world case examples

Larger group has split into 3 sub-groups.  If you wish to participate in one of the subgroups, please email the Secretariat, and indicate which group.   
—Patient Centricity
—Database of Instructive Case Histories
—Disease Registries

An increasing number of CNS studies are conducted under the orphan diseases umbrella; these studies pose a variety of special methodologic challenges including high placebo response, lack of accepted efficacy endpoints, lack of patient-centered quality of life endpoints, wide heterogeneity in patient presentation, heterogeneity of expected drug response, far-spread study centers, illness-related physical limitations on travel, and lack of research-trained investigators.

Approximately 7,000 diseases have been designated as “orphan,” (affecting less than 200,000 patients in US), with a high proportion of these occurring in childhood and thus qualifying for both pediatric and orphan drug regulatory incentives.  With these incentives in place for drug developers, it is likely that more and more ISCTM members will become involved with such studies and the methodologic challenges that characterize them. 

The working group will work toward identifying key issues, sponsoring symposia, suggesting best practices via ISCTM-approved white papers, and producing publications to help advance the field.
